The target population is adult patients with acute chest pain, but without obvious Acute Coronary Syndrome (ACS) on Electrocardiogram (ECG). Therefore, adult patients (>21 years old) with acute chest pain, for whom the provider orders troponins, and without evidence of an ST-segment elevation myocardial infarction (STEMI) on ECG, will be included. Based on STEMI rates at Wake Forest Baptist Medical Center (WFBMC) we expect less than 5% of patients with acute chest pain to be excluded due to ECG criteria.
